README

@arcwall/mcp-server

Security scanning for Claude Code, Cursor, Windsurf, and any MCP-compatible AI coding tool.

Setup

  1. Get your free API key at https://arcwall.io

  2. Add to your MCP config:

Claude Code (~/.claude/mcp.json):

{
  "mcpServers": {
    "arcwall": {
      "command": "npx",
      "args": ["@arcwall/mcp-server"],
      "env": { "ARCWALL_API_KEY": "your-key-here" }
    }
  }
}

Cursor (.cursor/mcp.json): Same config. Windsurf: Add via MCP settings panel.

  1. Restart your AI tool — Arcwall is ready.

Tools

  • arcwall_scan_secrets — hardcoded credentials
  • arcwall_scan_mcp — MCP config vulnerabilities
  • arcwall_scan_agent_instructions — CLAUDE.md, .cursorrules security
  • arcwall_threat_model — STRIDE analysis
  • arcwall_check_prompt — prompt injection testing
  • arcwall_pre_commit — pre-commit security check
  • arcwall_scan_dependencies — known CVEs in packages

Usage

Ask your AI assistant:

  • "Scan this repo for secrets"
  • "Check my MCP configs for vulnerabilities"
  • "Is my CLAUDE.md safe?"
  • "Generate a threat model for this project"
  • "Run a security check before I commit"
  • "Are there vulnerable packages in this project?"
